If there is one thing you see in business, it is many people carry around two phones. They use a personal phone and a business phone. RIM wants to change that by added new software that would handle the two separately. It is called Blackberry Balance. We'll see if it flies...

The goal behind the software is to let BlackBerry owners rely on a single smartphone, so they can use the same device for business and social reasons. IT administrators--concerned about personal devices tapping into their networks--will also be able to manage and secure the corporate side of the phone while leaving the personal side up to the user.

"There are two fundamental use cases on the smartphone--enterprise and personal. The problem is that they are conflicting," McDowell told Reuters.

As an example, people will be able to freely hop onto the Internet and use Facebook and other social-networking sites. But access to corporate e-mail through a BlackBerry Enterprise Server would be controlled by IT, with a virtual wall separating the two sides.

And then a user screws up and that "virtual wall" is gone and your corporate network is now open for everyone.

Scientists have managed to transform a radically different laser concept into a radically different laser reality.

It’s 30 micrometers long - that’s 30 millionths of a meter - eight micrometers high and has a wavelength of 200 micrometers. This makes the laser considerably smaller than the wavelength of the light it emits - a scientific first.

Is seems to be based on the same general principles that allow cell phones (and other portable wireless communication devices) to use an antenna that is shorter than one-quarter of a wavelength of the frequency it operates at.
